Vicary - Chiang US Open

Vicary,Elizabeth - Chiang,Sarah [A53]
US Open (6), 08.08.2008


1.e4 c6 2.c4 So I play this line still, although my coach keeps telling me to stop. His point is that I'm completely unprepared for 2...e5, and in fact perhaps I'm at sea after 2... g6 as well. It's just always worked so well for me, 2. c4--so disorienting for the opponent.Also she was a little kid, so I wanted to trick her somehow.

2...d6 But wow, this is a serious change of structure for a person who might or might not have any idea how to play a pirc.

3.d4 Nf6 4.Nc3 g6 5.h3 The lines I play against the pirc keep changing, really they change faster than I can't keep up with them, so I know nothing concrete about this position, but I can't see that her Bc8 has a decent square aside from g4.

5...Nbd7 6.Nf3 Nb6 I guess she hasn't heard the "Knights on b6 are always bad" rule. Maybe 6...e5 is playable?

7.Bd3 Qc7 8.Bf4


Try to find a decent move here. It's hard, right?

8...Qd8

If 8...Bg7, 9.e5 dxe5 10.Nxe5 was my intention, but Rybka prefers 9. c5 Nbd7 10. cxd6 exd6 11. 0-0

9.0–0 Bg7 10.Qe2

After a few moves, I was very upset with myself for putting the queen on e2, when it belonged on d2, and blamed this for making things harder than they had to be. But rybka likes it. How confusing.

Beastie also wants to play 10.e5-- I thought about this, but worried my center might dissolve. 10...dxe5 11.dxe5 Nh5 12.Bg5 Be6 13.Qe2; 10.Qd2 Be6 11.b3

10...0–0 11.Rad1 d5 12.cxd5

Here's a tactical line I never would have found: 12.exd5! cxd5 13.c5 Nbd7 (13...Nc4 14.Bxc4 dxc4 15.Qxc4) 14.Rfe1 Re8 15.Nb5.

12...cxd5 13.e5 Ne8


There are all kinds of ideas I want to play for the next 10 moves: h4-h5, f4-f5, Qd2, Bh6, Nf3-h2-g4, Re1–e3-g/h3 or maybe Kh2/Rh1/Kg1. Hard to choose.

14.Rfe1 Nc7 15.Qd2 Ne6 16.Bh6 Bd7 Here I couldn't decide if I should continue with attacking moves, Nh2-g4 or h4, or I should take two moves to restrict white on the queenside, with b3 and Ne2. I decided on the latter. Dunno which is best.

17.b3 Rc8 18.Ne2 Re8 19.h4 f6


20.Bxg7 Fritz and Rybka want to play 20.h5 g5 21.Bxg7 Kxg7 22.a4 Rc7 23.a5 Nc8 24.Rc1 but I'm never going to see an unforced line like that which switches plans.

20...Nxg7 At the time, I thought king takes was almost forced, but Rybka prefers Nxg7. However, the reason for the preference is the ridiculous computer line of the previous note, so it only half counts. [20...Kxg7 21.h5 g5 22.a4 Rc7 23.a5 Nc8 24.Rc1 Rxc1]


21.Ng3 Rybka prefers 21.Nf4 Bg4 22.Nxg6 hxg6 23.Bxg6 Nd7 24.Qf4+- (24.Qh6 Nf8) ]


21...Bg4 22.Qh6 Qd7 23.h5


23...Nf5

During the game I thought she would play this nice line:

23...Bxh5 24.Nxh5 Nxh5 25.e6 Now it does matter where the queen goes, because from c7, there might be a defence in Qc2, whereas on d6, the queen keeps an eye on the e6 pawn:

25...Qc7 26.Bxg6 hxg6 27.Qxg6+ Ng7 28.Qf7+ (28.Re5 fxe5) 28...Kh7 29.Re3 Qc2 30.Ng5+) 25... Qd6 26.Bxg6 hxg6 27.Qxg6+ Ng7 28.Re5 fxe5 (threat: 28...-- 29.Rg5 fxg5 30.Nxg5) 29.Ng5

24.Nxf5 gxf5 25.e6 Qd8 26.Nh4 Kh8 27.Nxf5 Rg8


28.Nd6! Rg7 29.Nf7+ Rxf7 30.exf7 f5 31.f3 Nd7 32.fxg4 1–0
